My stamina isn't a question, I box, and ran for hours...the problem is, those fukkers bite through metal at times....that might definitely be a problem.
My main goal would be to turn on X-Factor and maul each and everyone of those fukkers. I'm talking about devouring and popping off those tiny rat-munk heads. This works two fold in my favor, as their blood will keep me sustained, also those rat heads will keep my stomach full. Waves 1-3 will come at me strong but waves 4-10 will be hesitant in their approach, as I'm covered in the blood and fur of their former comrades....
With each new wave, I will let out a howl that echoes through the squirrel containment chambers, so that they know to shake in fear. While their motives are to kill me, mine is to be remembered in all of Squirrel kingdom, they will speak high and low of me, from tree trunk to green bush, they will know my name, my roar will shake the very foundation of every squirrel on its way to fight me.
